Taking Yofolvit with food and drinks

No interactions between Yofolvit and any food or drink are known.

Pregnancy and breastfeeding

Yofolvit is indicated for the prevention of iodine, folic acid, and vitamin B12 deficiencies before and during pregnancy, as it contains these three active principles in the recommended doses for pregnancy. The administration of potassium iodide, folic acid, and vitamin B12 to pregnant women in doses higher than the recommended daily doses should be done under medical control and evaluating the benefit-risk ratio.

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.

No effects on the ability to drive and use machines have been observed.

Yofolvit contains lactose and sodium

This medicine contains lactose. If your doctor has told you that you have an intolerance to certain sugars, consult with them before taking this medicine.

This medicine contains less than 23 mg of sodium (1 mmol) per tablet; it is essentially "sodium-free".

3. How to take Yofolvit

Follow the administration instructions of this medicine indicated by your doctor. In case of doubt, consult your doctor or pharmacist again. The normal dose is 1 tablet per day, preferably before meals.

If you take more Yofolvit than you should

If you have taken more Yofolvit than you should or in case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicology Information Service, phone 91 562 04 20.

Deliberate or accidental poisoning with this medicine is unlikely.

Taking doses much higher than those indicated in this leaflet or for long periods may cause metallic taste, burning sensation in the mouth and throat, painful sensitivity in teeth and gums, increased salivation, irritation of the nasal mucosa, sneezing, and irritation of the eyes with swelling of the eyelids (symptoms known as "iodism").

Severe headache, cough, pulmonary edema (fluid accumulation in the lung), and swelling and discomfort of the parotid and submaxillary glands (glands located below the lower jaw) may also occur. The pharynx, larynx, and tonsils may also become inflamed.

In oily areas of the skin (seborrheic areas), moderate rashes may appear, rarely severe rashes.

Gastric irritation (of the digestive system) is common when very high doses are ingested and may cause diarrhea, sometimes with blood in the stool.

The signs and symptoms of iodism usually disappear spontaneously after a few days of stopping treatment.

The use of high doses of potassium iodide or for long periods may cause hyperplasia of the thyroid gland (enlargement), goiter, and severe hypothyroidism (decreased thyroid function).

If you forget to take Yofolvit

Do not take a double dose to make up for forgotten doses. Simply take the forgotten dose when you remember and take the next doses with the indicated interval between administrations (24 hours).

If you stop taking Yofolvit

Your doctor will indicate the duration of treatment. Do not stop your treatment before, as it will not have the expected efficacy.

If you have any other questions about the use of this medicine, ask your doctor or pharmacist.
